- / per
Pseudofumaria lutea (syn. Corydalis lutea), the yellow corydalis or rock fumewort, native the south-western and central Alps of Italy and Switzerland, but widely introduced elsewhere.
The leaves are finely divided and yellow-green to gray-green, often remaining over winter (evergreen). The yellow flowers appear over along period, from late spring to autumn.
Yellow corydalis is hardy to -34 °C. It does best in light shade, but will tolerate both full sun and deep shade. It can grow wild in cracks in old walls where there is good drainage. Rare seeds.
Type: Hardy perennial
Hardiness zones: 4-9
Height: 15", 38cm
Location: Sun or shade
Seeds per packet: 10
Sow just under the surface of the soil and water in. Leave them at room temperature for 6 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 80 days. Be sure they stay moist. After the cold stratification period they are then brought back to a cool room (15-18C, 59-68F) for them to germinate. Germination can be erratic, generally 30-90 days after the warming period for most seeds, though some can take longer.
Ornamental use only. These seeds and/or plants are poisonous.
